IMPROVEMENT IN STOVE-DAMPER AND F LUE-STRIP.

Specification forming part of Letters Patent No. 197,632, dated November27, 1877; application filed July 30, 1877.

To all whom it may concern:

Be it known that I, GEORGE W. HERRICK, of. Detroit, in the county ofWayne and State of Michigan, have invented an Improvement the may becompelled to pass under the reservoir situated at the back of the stove,or

under the oven, as may be desired, all of which is more fullyhereinafter set fort Figure l is a perspective view of the rear I partof a cooking-stove, showing the back flues, warming-closet, place forwater-reservoir, and my improved arrangement of the dampers andflue-strips, with a portion broken away. Fig. 2 is a detachedperspective View of my improved dampers and flue-strips, and alsoshowing a modification of the same in dotted outline. Fig. 3 is asection through a threefiue cooking-stove, with my damper an dflue-strip in position, the rear part of the stove and thewarming-closet being cut on the dotted line in Fig. 1.

Like letters denote corresponding parts.

In the drawing, A represents a portion of the rear and main part of acook-stove, with a warming-closet, B, on the rear, above which is theflue-space 0, provided with a suitable opening for the reception of awater-reservoir,

or other vessel or vessels. Upon the top of the top plate of thewarming-closet it has been usual to cast or otherwise secureflue-strips, coincident with the flues. so that when the products ofcombustion were sent under the reservoir they would be carried under thebottom, and not pass directly to the exit.

D D are double'winged dampers, by which the side flues are opened orclosed at will, and to them are cast or otherwise secured the flanges orwings a a, so arranged that when the heat is diverted under the bottomof the reservoir or other vessel they will perform the functions offlue-strips, and direct the heat backward and under the reservoir beforeit passes to the exit b.

By this arrangement all the products of combustion can be compelled topass directly under the reservoir or other vessel upon that part of thestove, and thence to the exit or they may be compelled to pass down andunder the oven at will.

Thus it will be seen that the operation of the dampers D, entirelycontrol the passage of the products of combustion directly andseparately to either the reservoir or the oven, as may be desired.

The same end can be accomplished by omitting the dampers and flue-stripsarranged to operate in connection with the side flues; but,

in lieu thereof, they should be arranged to operate in connection withthe central flue, as shown in dotted lines in Fig.2. While this latterarrangement would virtually perform the same functions, it would not beas eifectual in its operation and control of the products ofcombusition, as Ihave found .by practical tests and experiments.

What 1 claim as my invention is The combined damper and flue-strip D D aa, constructed and arranged substantially as and for the purposesdescribed.
